Building channels of data…

Data can and SHOULD have an expiry date outside of our sphere of control. The European Union has tackled this. The Canadian governments have attempted to deal with this.

By using Open Source, and requiring all publicly funded software systems that handle people’s personal data should be required to use Open Source Software and Data Principles is one way.

This has been quietly happening in many governments and corporations.

Facts and Statistics

Statistics Canada’s Participation and Activity Limitation Survey (PALS) provides information on the prevalence of people with disabilities, their employment profile, education, their income, and their participation in society.

Total Number and Percentage of People with Disabilities in Canada •Approximately 3.6 million people in Canada have disabilities, representing 12.4 percent of Canada’s population.

Total Number and Percentage of People with Disabilities in Ontario• Approximately 1.5 million people in Ontario have disabilities, representing 13.5 percent of Ontario’s population.[1]

Disability Rate Increases with Age• Of the total Canadian population in 2001, 12.4 percent have a disability. National statistics indicate that 41 percent of people aged 65 and over have a disability, while among those aged 15 o 64, 10 percent have a disability. Of the total population of Canadian children aged 0 to 14, 3 percent have a disability.

Projected Statistics on Aging Population• Projections show that by 2021, seniors with disabilities will outnumber 25- to 64-year-olds with disabilities. In 2026, the majority of people with disabilities will be 65 years of age or older—some 3.05 million people.[2]

Education• Approximately 40 percent of adults with disabilities have a post-secondary education, compared to 48 percent of the non-disabled population.

The following table indicates the highest level of educational attainment for adults in Ontario ages 15 to 64:

 With Disabilities

 Without Disability

Less than high school

298 030 (37%)

1 606 550 (24%)

High school

193 320 (24%)

1 865 550 (28%)

Trades Certificate or diploma

92 650 (11%)

626 760 (9%)


136 310 (17%)

1 179 600 (17%)


93 700 (12%)

1 506 710 (22%)

• More women than men have completed college or university in the non-disabled population (42 percent versus 37 percent, a 5 percent differential), as well as in the population of people with disabilities (31 percent versus 25 percent, a 6 percent differential).

Employment• Over half (54 percent) of working age adults with disabilities are either unemployed or not in the labour force, compared to less than a quarter (24 percent) of working age adults without disabilities.[3]

• The employment rate for people with disabilities is 41 percent, compared to 76 percent for people without disabilities.

• The unemployment rate for people with disabilities (26 percent) is over 5 times higher than the unemployment rate for people without disabilities (5 percent).

The following table indicates the labour force activity for adults in Ontario, ages 15 to 64:

 With Disabilities

 Without Disabilities


336 120 (41%)

5 175 000 (76%)

Unemployed/Not in the work force

443 040 (54%)

1 610 070 (24%)

Trades certificate or diploma

36 780 (5%)

• A breakdown of the results by gender for Ontario adults indicates that 45 percent of men and 38 percent of women with disabilities are employed, compared to 81 percent of men and 72 percent of women without disabilities. This contrasts with the higher post-secondary education of women with disabilities.


• Total income is defined as the “total of income from all sources, including employment income, income from government programs, pension income, investment income, and any other money income.”

• Ontarians with disabilities reported an average income of $22 543, compared to $34 144 for the non-disabled population, a difference of over $11 000. Ontarians who have disabilities have an average income that is less than a third (33 percent) of the average income of people without disabilities.

• Nine percent of adults with disabilities have a total income of over $50 000, compared to 21 percent of the non-disabled population. Of the adults with disabilities who have incomes over $50 000, 14 percent of men have a total income of over $50 000, compared to 5 percent of women.

• Eighty-four percent of women with disabilities and 65 percent of men with disabilities reported income of less than $30 000.

• Forty-six percent of adults with disabilities in the labour force make less than $15 000 a year, compared to 32 percent of people without disabilities. Just over half (56 percent) of women with disabilities in Ontario’s labour force have a total income of less than $15 000, compared to approximately a third (33 percent) of disabled men.

The following table indicates the total income of adults with and without disabilities in Ontario, for ages 15 and over:

[1] Figures taken from Statistics Canada, Participation and Activity Limitation Survey (PALS), 2001, released in September 2003. Previous figures of 1.9 million Ontarians – 16 percent were taken from Statistics Canada, Health and Activity Limitations Survey (HALS), 1991. The difference in numbers can be partly attributed to a new survey methodology (e.g., PALS 2001 may have left out a substantial number of people with milder disabilities who had been included in HALS 1991) and to a new survey population (e.g., HALS 1991 included people living in health-related institutions and in the Yukon and Northwest Territories, while PALS 2001 only included people living in households in all provinces). Changes are explained in more depth in A New Approach to Disability Data: Changes between the 1991 Health and Activity Limitation Survey (HALS) and the 2001 Participation and Activity Limitation Survey (PALS) from Statistics Canada, available online at

[3]”Not in the labour force” includes students, homemakers, retired workers, and seasonal workers in an “off season,” and people who cannot work because of a long-term illness or disability.


Essentially this is the point of concern in Ontario. With the occuring review of legislation regarding accessibility of various locations around the province which involves the following measurements for the size of the population who are “People with Disabilities in Ontario” as 1.5 Million people or 13.5 % of the total population of just over 12 Million (2011 Stats Can).

(1)Total Number and Percentage of People with Disabilities in Ontario• Approximately 1.5 million people in Ontario have disabilities, representing 13.5 percent of Ontario’s population.[1]

This legislation doesn’t affect this group of 1.5 million people, it affects everyone of us in Ontario.

Disability doesn’t discriminated and anyone can become disabled. 

I will be updating this note and sharing information through my website(s).

A reprint of the Hacker’s Manifesto

Title : Hacker’s Manifesto

                               +++The Mentor+++

                          Written on January 8, 1986

        Another one got caught today, it's all over the papers.  "Teenager
Arrested in Computer Crime Scandal", "Hacker Arrested after Bank Tampering"...
        Damn kids.  They're all alike.

        But did you, in your three-piece psychology and 1950's technobrain,
ever take a look behind the eyes of the hacker?  Did you ever wonder what
made him tick, what forces shaped him, what may have molded him?
        I am a hacker, enter my world...
        Mine is a world that begins with school... I'm smarter than most of
the other kids, this crap they teach us bores me...
        Damn underachiever.  They're all alike.

        I'm in junior high or high school.  I've listened to teachers explain
for the fifteenth time how to reduce a fraction.  I understand it.  "No, Ms.
Smith, I didn't show my work.  I did it in my head..."
        Damn kid.  Probably copied it.  They're all alike.

        I made a discovery today.  I found a computer.  Wait a second, this is
cool.  It does what I want it to.  If it makes a mistake, it's because I
screwed it up.  Not because it doesn't like me...
                Or feels threatened by me...
                Or thinks I'm a smart ass...
                Or doesn't like teaching and shouldn't be here...
        Damn kid.  All he does is play games.  They're all alike.

        And then it happened... a door opened to a world... rushing through
the phone line like heroin through an addict's veins, an electronic pulse is
sent out, a refuge from the day-to-day incompetencies is sought... a board is
        "This is it... this is where I belong..."
        I know everyone here... even if I've never met them, never talked to
them, may never hear from them again... I know you all...
        Damn kid.  Tying up the phone line again.  They're all alike...

        You bet your ass we're all alike... we've been spoon-fed baby food at
school when we hungered for steak... the bits of meat that you did let slip
through were pre-chewed and tasteless.  We've been dominated by sadists, or
ignored by the apathetic.  The few that had something to teach found us will-
ing pupils, but those few are like drops of water in the desert.

        This is our world now... the world of the electron and the switch, the
beauty of the baud.  We make use of a service already existing without paying
for what could be dirt-cheap if it wasn't run by profiteering gluttons, and
you call us criminals.  We explore... and you call us criminals.  We seek
after knowledge... and you call us criminals.  We exist without skin color,
without nationality, without religious bias... and you call us criminals.
You build atomic bombs, you wage wars, you murder, cheat, and lie to us
and try to make us believe it's for our own good, yet we're the criminals.

        Yes, I am a criminal.  My crime is that of curiosity.  My crime is
that of judging people by what they say and think, not what they look like.
My crime is that of outsmarting you, something that you will never forgive me

        I am a hacker, and this is my manifesto.  You may stop this individual,
but you can't stop us all... after all, we're all alike.

                               +++The Mentor+++

There is a spirit of an archetype that is being expressed here. Mainstream media has attempted to hijack the word, “hacker” and paint it with a brush of criminality alone and this is short sighted and illogical at best.

Hacker also does not have to just deal with technology. The spirit of Hacking, lends itself to all forms of creations. Knitters aka Yarn Hackers. Home brewers aka Beer Hackers

If you have a passion and succeed at it and demonstrate the “chops” within a “field” then by definition you have “hacked” your way into that field or industry, profession or vocation.

Ultimately, it is about life long learning.

12 Factors


Great Resource.

The Twelve Factors

I. Codebase

One codebase tracked in revision control, many deploys

II. Dependencies

Explicitly declare and isolate dependencies

III. Config

Store config in the environment

IV. Backing services

Treat backing services as attached resources

V. Build, release, run

Strictly separate build and run stages

VI. Processes

Execute the app as one or more stateless processes

VII. Port binding

Export services via port binding

VIII. Concurrency

Scale out via the process model

IX. Disposability

Maximize robustness with fast startup and graceful shutdown

X. Dev/prod parity

Keep development, staging, and production as similar as possible

XI. Logs

Treat logs as event streams

XII. Admin processes

Run admin/management tasks as one-off processes


In the modern era, software is commonly delivered as a service: called web apps, or software-as-a-service. The twelve-factor app is a methodology for building software-as-a-service apps that:

  • Use declarative formats for setup automation, to minimize time and cost for new developers joining the project;
  • Have a clean contract with the underlying operating system, offering maximum portability between execution environments;
  • Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration;
  • Minimize divergence between development and production, enabling continuous deployment for maximum agility;
  • And can scale up without significant changes to tooling, architecture, or development practices.

The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc).


The contributors to this document have been directly involved in the development and deployment of hundreds of apps, and indirectly witnessed the development, operation, and scaling of hundreds of thousands of apps via our work on the Herokuplatform.

This document synthesizes all of our experience and observations on a wide variety of software-as-a-service apps in the wild. It is a triangulation on ideal practices for app development, paying particular attention to the dynamics of the organic growth of an app over time, the dynamics of collaboration between developers working on the app’s codebase, and avoiding the cost of software erosion.

Our motivation is to raise awareness of some systemic problems we’ve seen in modern application development, to provide a shared vocabulary for discussing those problems, and to offer a set of broad conceptual solutions to those problems with accompanying terminology. The format is inspired by Martin Fowler’s books Patterns of Enterprise Application Architecture and Refactoring.

Who should read this document?

Any developer building applications which run as a service. Ops engineers who deploy or manage such applications.

Maker Movement is here to stay…

and truly it has always been here. More recently it seems to be coming into broader awareness and that’s a good things.  It is when we collectively come together to build and improve our communities at the grassroots level, do we see the most progressive and productive processes and policies arise among the community because they all collectively are interested in a Best for All choices that support and advance everyone’s interests.

We have interests, skills, abilities, talents and gifts. How we express them in the world is how we give back to the world that we live in and on.

We all have the ability to create and contribute and give back to our community that we live in.

How, When, Where and What we do  — be aligned with our personal peace and for the greatest benefit of all including yourself.
